16 Claims.

This invention relates to a copy holder and has for an object the provision of such a device which may be extended to a height greater than that of the average copyholder, and yet which in its lowered position is adapted to be conveniently received and permanently positioned in a typewriter enclosing desk, the device being then about the same height as the ordinary typewriter.

Another object is to provide a copy holder of the kind described provided with a novel, simple and efficient operating means.

Another object is to provide a device of this kind having a new and efficient type of support r for copy pages.

Another object is the provision of a copy holder of the kind set forth which is of simple and permanent construction and smooth and :simple in operation.

These ands other objects are attained by the means described herein and illustrated in the accompanying drawings, in which:

Heretofore copy holders have been commonly constructed oi two principal parts, namely, an immovable copy holder section and a movable (Cl. 1Z0-29) section adapted to be raised above the immovable section during use. Obviously to be adapted for extension to the height usually necessary during use of a copy holder, the sections of the devices such as described, have had to be of considerable height individually with the result that, even in lowered inoperative position, they were of such height as to extend a considerable distance above the ordinary typewriter, so that it was necessary to remove the copy holder from its operative position behind a typewriter when it was desired to close the typewriter enclosing desk.

These diiiiculties have been overcome by the present invention which provides for a copy holder comprising an extensible frame of telescopically associated parts which may be raised to a height greater than heretofore possible and yet, due to the telescopic structure, may be lowered to a nested or unextended position at which time the height of the device is no greater than that of the average typewriter so that the copyholder may be permanently retained in the typewriter enclosing desks now commonly utilized.

Another important feature of the present nvention is the curtain-like support for copy pages which is drawn upwardly simultaneously with the extensible frame of the copyholder, and which, in its unextended position, occupies a minimum of space. In addition to this, the` work support referred to is a highly desirable substitute for the heavy and unwieldy sheets of metal now commonly utilized in copy holders for supporting the copy pages. Other advantages and improvements are provided by the present invention and which will appear in the course of the following description.

1n the drawings the copy holder is shown as comprising a base I2 of rectangular shape in plan and which' may beprovided with a narrow upturned flange I3 around the greater part of its periphery. An extensible frame is mounted on this base. The frame comprises a paii` of parallel standards I4 and I5 each consisting of a plurality of telescopically associated tube sections, the respective tube sections of one standard being of substantially identical dimensions with the respective tube sections of the other standard. These tube sections are shown in extended relationship in Fig. 3 wherein each standard comprises the widest or lowermost pair of tube sections I6 and the succeeding pairs I 'I, I8, and I9 of progressively diminishing diameter. The lowermost pair I6 of tube sections may be xed to the base I2 by means of sleeves 29 and TH, each embracing the lower end portion of one of the tube sections i6 and having extending therebetween an integral rigid vertical wall 22. Said sleeves and integral wall may be provided at the bottom with right angle ange portions adapted to be spot welded to the base I2 or secured in any suitable manner. The upper ends of said sleeves 2c and 2I are formed to provide clamp portions 23 and 24, Fig. 3, adapted to embrace and be tightened about the pair of tube sections I6. It is obvious that the standards, by this means, may be readily mounted upon and removed from the base i2. The bottom ends of each succeeding pair of tube sections extend some distance into the tube sections next below so as to preclude wobbling of the tube sections in their raised positions. In addition to this, the upper ends of the tube sections are constricted or pinched as at 25 so that each tube section will snugly embrace the next succeeding section. The tube sections are precluded from separation by means of small lugs 25 which are struck inwardly of the tube sections and the extreme lower ends of the removable tube sections are flared as at 21, Fig. 3, so as to strike against the inwardly projecting lugs 2E whereby further upward movement of' the tube sections is preeluded.

A top piece 23 extends transversely between the standards and is xed adjacent each side to the innermost pair I9 of the movable tube sections. This top piece may be formed on its top and sides with rearwardly projectingr flanges 29 and 3S and the tube sections I9 are secured to the top flange by projecting a headed pin 3l, Fig. 3, downwardly through said iiange into the upper ends of said tube sections I9, a set screw 32 being utilized for xing the pin in place. For further supporting and securing the upper ends of the tube sections I9, a pair of substantial V- shaped brackets 33, Fig. 3, is provided. Each tube section I9 passes through the midsection of one of the brackets 33 and the latter is formed at its upper ends with outwardly projecting anges 34 which are suitably secured such as by spot welding to the inner face of the top flange 29. Immediately beneath each bracket 33 a pair of cushion Washers 35 may be positioned about tube sections I9 to serve as shock absorbers when the tube sections are dropped to their nested relationship when said cushion washers are disposed immediately adjacent the tops of the lowermost tube sections I6. The top piece 28 is further provided with a clamp member 36, the cross bar 31 of which is urged into contact against the front face of top piece 2B whereby copy pages may be clipped to the copy holder. For retaining the upper portions of copy pages, a coil spring 38 may be attached to the upper face of the top flange 29 of top piece 28.

The extensible frame just described is adapted to have associated therewith a curtain-like support 39 adapted to support copy pages in proper position to be read. Said curtain-like member comprises a roll 49 of suitable sheet material, such as latex, which is wound about a spring roller 4I of the kind commonly utilized for window shade rollers. This roller 4I has its ends mounted in brackets 42 and 43, Fig. 3, the inner ends of the brackets being clamped as at 44 to the xed pair I5 of tube sections. The outer end of the sheet material 39 is attached to the top piece 28. For this purpose said outer end of the sheet material has attached along its edge a light metal binder 45. At the middle the binder has an aperture which is adapted to be engaged by a hook 46, Fig. 2, struck out from the lower portion of top piece 28. By these means the sheet material 39 may rapidly be removed from operative position when so desired. An eye guide 4'! is hingedly associated with the upper ends of the fixed tube sections IB. This eye guide may consist of a suitable length of strip material extending transversely of the extensible frame in front of the curtain-like work support described. Along its bottom edge the eye guide is turned upon itself at 48, Fig. 2, to form a journal through which extends the transverse portion 49 of a wire frame 59. Just behind the eye guide strip 47 the wire frame 59 is bent inwardly at right angles to provide the bent sections 5I, Fig. 3, about which suitable cushion sleeves 52 may be disposed. The lower ends of the wire frame 50 are again bent inwardly and embraced by journal plates 53 which are secured to the ends of a transversely extending bar 54 secured to the upper ends of the fixed pair I6 of tube sections. This structure likewise is clearly seen in Fig. 3. It may be here remarked when the wire frame 50 of the guide is turned up in the position seen in Figs. 2 and 3, the cushions 52 are adapted to limit downward or collapsing movement of the extensible frame at a point above the completely collapsed condition of the frame. This limiting movement is effected by striking of the lower ends 399 of the lateral flanges 39 of said top piece 23 against the cushion members 52. This piece is seen in Fig. 2 and is the initial operative position of the copy holder, that is to say, the position at which the top portions of copy pages are most conveniently visible. By further reference to Fig. 2 it will be obvious that the upper edge portions of copy pages are clipped beneath transverse bar 37 and the portion to be copied first will be seen by the operator immediately beneath said bar. Thereafter, as the work is copied, the copy pages, the extensible frame, and the sheet material 39 are progressively raised above the positioned eye guide 47, all of which is well understood by those acquainted with the use of copy holders.

The progressive raising of the extensible frame is accomplished by novel means comprising a coil of steel tape 55. This tape is preferably arcuate in cross section so that in extended position it possesses considerable rigidity. This kind of steel tape, as is well known, is adapted 'to be rolled flat and in the present instance is coiled within a casing 56 mounted on the base I2. The tape is adapted to pass upwardly through an outlet 5l' in the casing 5S and between a pair of pressure rollers, the outer end of the steel tape being ixed as at 58 to the top piece 28, that is to say, it may conveniently be Xed upon a block 59 depending from the inner face of the top iiange 29 of said top piece. Means are likewise provided for precluding buckling of the extended tape so that when the latter is fed upwardly by the pressure rolls, the extensible frame as a whole is likewise raised, said means to be later described.

The pressure rolls referred to comprise a roller 69 having a convex periphery and mounted fixedly at the end of a shaft 6I, Fig. 3, which extends laterally of the extensible frame. The inner end of said shaft 5I is journaled in a suitable support plate 62 to which the tape casing 55 may likewise be conveniently secured, as at 63. The roller 60 and associated structure is mounted at the rear of lthe vertical wall 22 heretofore mentioned (Fig. 2).

This wall 22, adjacent the middle, is provided with an upward extension 64 which is apertured in the middle for a purpose to be now described. A second pressure roller 65 is mounted to project through the aperture just mentioned and to bear forcibly against the periphery of the roller 60, that is to say, against the tape which passes between these rollers. The roller is of concave shape in its periphery to correspond with the convex periphery of roller 60, the rollers being thus adapted to snugly engage the steel tape of arcuate cross section.

Roller 65 is provided with a short stud shaft 66 projecting laterally of the roller and which projecting portions are engaged by the upper ends of a pair of spring strips 61 and 68. The upper ends of said spring strips are hook shaped for engaging the stud shaft 66. The spring strips 61 and 68 are held in place and urged against the vertical wall 22 by means of a suitable clamp 69 secured to said wall. The ends of stud shaft 66 are likewise engaged at each side of the roller by a U-shaped bracket 10, the ends of which are formed to provide hook members 1| that embrace the ends of said shaft on the opposite sides thereof from the journal members of said spring strips. (Fig. 2). The end edges of the bracket 10 are straight as shown at 12 and the bottom portions of the ends of the bracket are rounded as at 13 to provide a pair of fulcrum points or heels, the function of which will be later described. The straight end edges 12 of the bracket are held against the flat face of the wall extension 64 by the pressure of the spring strips 61 and 68.

Extending transversely of the bottom of the copy holder and substantially in a line with the top of the vertical wall 22 is an elongated arm 14 which is the primary means operative upon the pressure rollers for releasing pressure therebetween. Adjacent its middle, this arm is formed with an extended portion shaped like a bracket comprising the outwardly extending part 15, Fig. 2, and the vertically extending part 16 which projects upwardly in close proximity to the outer face 11 of the bracket 10. At the top, the vertical portion 16 is turned over to provide a fiange 18 which rests upon the top outer edge 19 of the bracket 10 and thereby holds the arm 14 in its normal position. The left end of arm 14, as seen in Fig. 1, is prevented from rising upwardly during operation of the arm by means of a small strip member which overhangs and slidably embraces the adjacent end of arm 14. The opposite end and adjacent portion of the arm 14, as seen in Fig. 1, extends downwardly at an angle and the extreme end portion 8| projects through a slot, Fig. 4, provided in a support plate 83 secured at this end of the base I2. This end 8| of the arm 14 is adapted to cooperate with the copy holder operating means to be now described.

The means for controlling the copy holder comprise a ratchet mechanism disposed in a casing 82 fixed to the support plate 83 and provided on its outer side with a removable cover 84, Fig. l. With reference to Figs. 4, 5, and 6,

l the ratchet mechanism comprises a ratchet wheel ratchet Wheel 85 a pivot. plate 86 is rotatably mounted upon the shaft 6| and at the upper left hand corner of the pivot Yplate 86 an upper pawl 81 is pivotally mounted and urged by a spring 88 into engagement with the teeth of the ratchet wheel. A spring 89 cooperating with the pivot plate 86, urges the latter downwardly into contact against a stop 90 projecting inwardly of the casing. On the lower left hand corner of the pivot plate 86, a stud member 9| is fixed, the latter being formed adjacent its outer end with an annular Way 92, Fig. l. A lower pawl 93 is mounted in the casing beneath the ratchet wheel 85, being spring urged into engagement with the teeth of said wheel and serving to preclude rotation of the wheel in a counter-clockwise direction. Forwardly of the ratchet casing 82 a bifurcated fulcrum member 94 is fixed to the base I2 and has pivotally mounted between its upper ends, as at 95, the operating lever 96 by which the copy holder is raised and lowered. The inner end of the lever 96 is bent as at 91 so as to enter within the ratchet casing 82 through slot 98 provided therein (Fig. 2). Said inner end of the lever 96 is` disposed beneath thestud member 9| and is adapted to ride within the groove 92 of said stud member. y

When the outer end of the lever 96 is pivotally moved downwardly by an operator, the inner end bears against the stud member 9| and carries the pivot plate 86 and upper pawl 81- upwardly in a clockwise direction to substantially the position illustrated in Fig. 6 which represents the limit of this movement of the lever. At the time of this movement, the pawl 81 engages the ratchet wheel and rotates the latter: as well as the shaft 6| to which it is fixed. This rotary movement is transmitted by the shaft 6| to the rear pressure roller 60 and con` sequently the tape 55, tightly engaged -by its pressure rollers, is fed upwardly upon each of such movements of the lever. 'Ihe spring` 89l returns pivot plate 86 and the lever 96 to ltheir initial position, during which return movement, the teeth of the upper pawl 481 merely ride or slip over the teeth of the ratchet. In this manner, the copy holder may be raised to the ltotal height of the extended tube sections, as illustrated in Fig. 3. To preclude buckling of the extended tape, a series of telescopically associated channel members 99, |00, |0|, |02 and |03 top of each of these channel members the end portion thereof is constricted as seen at |05, Fig, 9, while the lower end portion of the next succeeding channel member is flared or dis-` tended to provide a shoulder as shown at |06,y so as to engage the portion |05 of the preceding channel member whereby upward movement of the various component parts of the structure is limited. It will further be seen in Fig. 9 thatl shoulder |06 is disposed a considerable distance above the lower end of the channel member with which it is associated so that the extreme lower end portions of the channel members serve to give rigidity to the anti-buckling device in its extended position. The uppermost or innermost. channel member |03 has its upper end xed ,ask at |01 to block 59 projecting downwardly from'` the inner face of the top flange 29 of the top piece 28, as previously described.

For lowering the extended copy holder, the outer end of the lever 96 is moved upwardly at which time its inner end bears down against the outer end 8| of the release arm 14 associated with the pressure rollers. At this time the flange 18 of the bracket member heretofore described as integral with the arm 14, carries the outer end of the bracket member 'l0 downwardly, that is to say, the member 'lil is pivotally moved from the position seen in Fig. 2 to the position illustrated in Fig. 7. At this time the fulcrum portions 13 of the bracket 'l0 swing around into contact with the face of the wall extension 64' and thereby force the roller shaft 66 and roller 65 forwardly or out of snug engagement with the steel tape and roller 60 whereby the tape is released and all the component parts of the elevated copy holder, including the tube sections, the anti-buckling means described and the extended sheet material for supporting the copy pages, return to their unextended position, the sheet material being rerolled by virtue of its spring roller and the other parts of the copy holder falling of their own weight into nested relationship. It should be here noted that when the copy holder is to be lowered into completely inoperative position, the eye guide frame 58 is lowered by forward hinged movement thereof so that the cushion members 52 will not limit downward movement of the top piece 28, whereby the various tube sections assume their most completely nested relationship with the tops of the tube sections disposed close together adjacent the tops of the lowermost or xed sections I6. This relationship may be understood by reference to Fig. 2 wherein the nested relationship of all the tube sections except the innermost sections may be seen at |09. It will be seen in Figs. 1 and 2 that outward movement of the operating arm 'I4 from the wall 22 is precluded by a suitable guide |08 attached to said Wall by the same retaining means utilized for -the spring arm clamp 69.

The device is readily assembled and disassembled and may be permanently positioned behind a typewriter in a typewriter enclosing desk, at which time the operating lever 96 extends forwardly and at the right hand side of thetypewriter in a position to be conveniently manipulated by an operator.
